6 Claims. (Cl. 36-245) This invention relates to shoes, and moreparticularly to the heel and sole construction of a shoe.

The general object of my invention is to provide an improved heel andsole construction for a shoe,-which will greatly facilitate repairing ofthe shoe when it becomes worn.

A more particular object is to provide an improved heel construction fora shoe, by-means of which the heel is detachably held firmly in positionon the shoe and may be readily removed from the shoe when worn down andreplaced by a new heel.

Another object is to provide a heel construction for a shoe of thecharacter stated, by means of which the heel is detachably held firmlyin position on the shoe by means of a single screw, whereby a worn heelmay be readily removed from the shoe and replaced by a new heel.

Another object is to provide an improved heel and sole construction fora shoe, whereby the rear end of the sole may be held securely inposition on the shoe without nailing said end of the sole to the upperpart of the shoe.

Another object is to provide an improved construction of a shoe wherebythe heel may be removed from the shoe without injury to the heel or anyother part of the shoe. I

Another object is to provide an improved shoe construction including anovel metal cup to receive the heel of the shoe, for properlypositioning and firmly holding the heel in place on the shoe.

Other objects and advantages will appear hereinafter as thisspecification progresses.

My invention is illustrated in the annexed drawing forming a part ofthis specification, in which:

Referring more particularly to the annexed drawing, in which the sameparts are designated by the same reference numerals in all of thefigures, my improved shoe construction includes a three-quartersole 1,a;heel base 2, an inverted heel cup 3, a heel spacer 4, a detachableheel 5, an upper 6, and an insole 7 detachably fitted in the lower sideof said upper upon the upper wallof the cup 3 and heel base 2 within theinturned flange 6' along the lower edge of said upper 6.

hired States Patent 9 The heel base 2 is formed with a forward extension8, the under side of which extension is inclined upwardly and forwardlyas indicated at 9, from a line 10 extending across said under side ofsaid heel base 2 at the forward side of the opening in the heel base 2for the cup 3, to the thin feathered edge 11 of said forward extension8. The upper side 12 of a rear portion 13 of the three quarter sole 1 isinclined downwardly and rearwardly to the lower side of the sole 1 froma line 14, extending across said upper side of said sole, to the rearthin feathered edge 15 at the lower side of said sole, which inclinedupper side 12 of the rear portion of the sole 1 fits against theinclined lower side 9 of the forward extension 8 of said heel base 2.

The inverted heel cup 3 is formed with a vertical wall 16 depending froman upper horizontal wall 17 through a cup-shaped opening 18 in the heelbase 2 and through a corresponding opening 19 in the spacer 4. Thevertical wall 16 is formed with a forward straight inner end section 20extending transversely of the heel base 2, opposite side wall section 21extending rearwardly from the ends, respectively, of said forwardstraight transverse wall section 20, and an arcuate rear end wallsection 22 extending from the rear ends, respectively, of said side wallsections 21, said wall sections of the cup wall 16 extendingsubstantially parallel to the horizontal outline of the heel 5 and thecup 3 being of smaller area than that of said heel. The outlines of theopenings 18 and 19 in the heel base 2 and the spacer 4, respectively,conform to the outline of the wall 16 of the cup 3, and said wall 16 ofsaid cup fits the walls of said openings 18 and 19 in the heel base 2and spacer 4, respectively. The upper horizontal wall 17 of the cup 3 isof greater area than the area of the cup receptacle, as defined by thevertical cup wall 16, so that said upper horizontal wall extendsforwardly beyond said vertical wall 16 in the form of an external uppercup flange 23 around the of the cup 5 is provided a screw hole 24 forthe purpose hereinafter more fully described.

The heel spacer 4 is formed with an outer edge 25 which corresponds tooutline of the heel 5, and said spacer is provided with the opening 19of such shape and size as to receive the vertical wall 16 of the cup 3and fit snugly around the outside of the lower portion of said verticalwall, which lower portion of said vertical wall depends a short distanceequal to the thickness of said spacer below the heel base 2.

The detachable heel 5 is preferably formed of rubber, and a wood block26 is vulcanized at its base in the upper part of said heel, as at 26,and extends upwardly thereheel spacer 4.

from in the outline form of the inner side of the vertical wall 16 ofthe cup 3 to fit snugly within said cup wall when said heel is placedagainst the under side of the In substantially the center of said heelblock 26 is bored a screw hole 27 from the upper side of said block inalignment with said screw hole 24 in the upperwall 17 of the cup 5,toreceive the lower portion of a screw 28 which is extended downwardlythrough said screwhole 24 in said upper cup wall 17 of the heel cup'3and driven into the screw bore 27 in the heel block 26 for. drawing saidblock into the lower end of the,

ably held securely in position on the heel base 2. A heel pad 39 isplaced in the heel portion of the shoe upper .6 over the insole 7 andthe countersunk head of the screw .23, and upon the inturned flange 6 ofthe upper 6.

The operation of my invention is as follows:

The inturned flange 6' at the lower edge of the rear and sides of theheel portion of the upper 6, is first placed against the rear and sideedge portions 2' at the upper side of the heel base, and said upperflange 6 is then nailed or sewed to said rear and side edge portion 2'of said heel base. The heel cup 3 is then placed in the heel base 2,with the vertical cup-wall 16 depending downwardly from the horizontalcup-wall 17 through the cup-shaped opening 18 in said heel base 2, andwith said horizontal cup-wall 17 resting against the upper side of saidheel base within the inner edge of the inturned upper flange 6 at thelower edge of the heel portion of said upper. The three-quarter sole 1is then place against the lower side of the upper 6, with said sole nearits side and toe edges against the inturned flange 6 at the lower edgesof the corresponding side portions and toe of the upper 6, and withupper inclined surface 12, at the rear end of said sole 1, overlappingthe lower inclined surface i of the forward extension 8 of the heel base2, which inclined surfaces 12 and 9 of the sole and the heel base,respectively, are cemented together with a rubber cement, which cementholds said overlapping ends of said sole 1 and heel base 2 securelytogether without nailing or sewing said overlapping ends together. Thespacer d is then placed over the lower projecting end portion of thevertical wall 16 of the cup 3 against the under side of the heel base 2and against the under side of the tapered rear end portion of the sole1, with the outer side of said projectim vertical cup wall 16 fittedsnugly in the cup opening 19 in said spacer 4, and with said reartapered end of the sole 7 fitted tightly between the upper side of saidspacer 4 and the rear end portion of the lower inclined side of the heelbase extension 8. The heel 5 is then placed with its upper side againstthe lower side of the spacer 4 with its upstanding block 26 fittedsnugly in the cup 3, within the vertical wall 16 of said cup, and thescrew 28 is inserted downwardly through the screw hole 24 in the uppercup wall 17 and into the screw bore 27 in the heel block 26, whereuponsaid screw is turned and driven by a screw driver into said screw bore27 until the heel S is drawn up tightly against the spacer 4 and theblock 26 is drawn tightly within the cup wall 16, thus detachablyholding the heel 5 securely in position against the lower side fthespacer l and against turning, upon the heel base 2. The insole 7 is thenplaced in the bottom of the shoe upper 6 upon the inturned flange 6 ofsaid upper with the heel portion of said insole extending over andcovering the head of the screw 23.

When it is desired to remove a heel from the shoe, for example, when theheel is worn down, it is only necessary to lift the pad 30 from over thehead of the screw 28 and then turn said screw to unthread the lower endthereof from the screw bore 27 in the heel block 5, whereupon the heelmay then be withdrawn directly from the shoe.

Upon removal of a heel 5 from a shoe, said heel may be replaced byanother duplicate heel 5, and secured in position on the shoe by thescrew 28 in the manner here inabove described.
